DOUBLE-TRACK CABLE OR ELECTRIC ROAD.

SPECIFICATION forming part of Letters Patent No. 335,560, dated February9, 1886.

Application filed October 7, 1885. Serial No. 179,262.

T to whom, it may concern.-

Be it known that I, CHESTER BULLooK, a citizen of the United States,residing in Kansas City, in the county of Jackson and State of Missouri,have invented a new and useful Conduit for Double-Track Cable orElectric Railways, of which the following is a specification.

My invention relates to improvements in conduits for double-track cableor electric rail- [0 ways; and the object of my invention is toconstruct and arrange a conduit provided with two slots, one openinginto each track by the side of the inner rail of said track, so as torequire but one conduit for double-track cable 1 or electric railways,where traction-cable or electric wires can be placed and operated fromunder the bed of each track, to so construct and arrange the slot ofeach track as to use the inner rail of each track for the inner slotrailof each slot, respectively, so that the railways can be constructed andkept in repair without disturbing so much of the street, and at a greatsaving of cost, as compared with the usual manner of constructing aconduit for each track. -It is constructed under and between thetracks,extending from a point under the road-bed of the outer goingtrack to a point under the road-bed of the returning track, givingsufficient roo1n--about twelve inchesfor the cable of a cable road orthe electric wire for an electric road to be placed and operated throughthe slot by the side of the inner rail of each track, through which isto pass the stem of the grip that attaches the car or dummy to the cableor the stem of the brush that conducts the electric current to thedynamo or receiver for electric roads. The conduit is sustained byyokes, of wood or metal, placed about four feet apart along the line of4.0 the road, while the sides and bottom are lined with tile,concrete,wood, or metal. The inner ends of the cross-ties of each track rest uponand are secured to the outer posts of the yokes, thus uniting thetracks, while the inner 5 posts of the yok es are placed each side fromthe center and under the inner rail of each track and sustain thecovering of the conduit between the tracks, the inner posts being placedeach side from the center, leaving a space of about twenty inches,sufficient for (No model.)

workmen to pass through while the road is in operation, for oiling,cleaning, repairs,&c. The opening in the sills of the yoke, togetherwith this space, gives ample drainage for the conduit. I attain theseobjects by the mechanism illustrated in the accompanying drawing, whichrepresents a vertical section of the conduit below the surface of thestreet, with the slots on the inside of the inner rails of each track,with one set of car-wheels with axles on 6 one of the tracks.

Similar letters refer to similar parts throughout the views.

A represents the car-wheels and axle on one of the tracks; B, the slotsfrom the conduit 6 through which the stem of the grip or electric brushpasses while transmitting the power from the rope or wire to the car ordummy; O,the cross-ties on the road-bed and under the timbers thatsustain the rails; D, the outer posts of the yoke, which help sustainand are secured to the inside end of the cross-ties; E, the pulleys thatcarry the cable; F, the inner posts that sustain the covering betweenthe tracks, and also sustain the inner rail of each track; G, theopening through the sill of the yoke for drainage; H, the sill of theyoke; L, the flanged iron plates secured to the upperend of the posts F,and which sustain the covering of the conduit; N, the planks coveringthe conduit, extending from yoke to yoke and resting upon plates L;a,the inner rail of each track, being the inner slot-rail of each slot;a, the outer slot-rail of each slot; a, the outer rail of each track;I), the timber under the outer slot-rail, a, to which said rail isspiked; b, the timber under the inner rail of each track and under theinner slot-rail of each slot; 0, the timber under the outer rail of eachtrack; d, the paving-blocks of the street. 0

\V represents the electric wire for electric roads, as shown in theconduit; WV, the brace on which the electric wires are placed and heldin position at the side of the slot leading from the conduit. The cablefor cable roads 9 5 or the electric wires for electric roads are placedin the conduit to the outer side of a perpendicular to the slot of theconduit, thus carrying them under the bed of the track,that the powercan be transmitted from the cable 16c or wire to the outer going carthrough one slot and to the returning car through the other slot.

Having described my invention, What I de sire to claim and secure byLetters Patent is 1. A conduit for double-track cable or electric roadsextending under and from a point inside of the inner rail of one trackto a point mounting the cables or electric conductors outside of aperpendicular line through said slotopening, substantially as set forth.

8. The inner posts of the yoke that sustain the covering of the conduitbetween the tracks placed under the inner rails of the tracks and eachside from the center of the sill, leaving a' space through the conduitfor workmen and for drainage; in combination with traction-cablef-;.;:-

or electric wires, as shown, and for the purpose set forth. 4. Indoubletrack cable or electric railways, a transverse yoke between thetracks, a

also extending from a point under the road bed of one track to a pointunder the road-bed of the other track, supporting the inner end of 7 thecross-ties of each track and supporting the inner stringer and rails ofeach track, as described, and for the purposes set forth.
